**What is tested?**

The provided benchmark tests two approaches to accessing a nested object property in JavaScript:

1. **Lodash.get**: This approach uses the popular Lodash library, which provides a convenient way to access nested objects. The `_.get()` method takes an object and one or more keys as arguments and returns the value associated with those keys.
2. **Native (Property dot notation)**: This approach uses the native JavaScript syntax for accessing nested object properties.

**Options compared**

The benchmark compares two options:

1. **Lodash.get**: Uses the `_.get()` method from Lodash library to access the nested property.
2. **Native (Property dot notation)**: Uses the native JavaScript syntax `myObj.cars.car1` to access the nested property.

**Pros and Cons of each approach**

* **Lodash.get**:
	+ Pros:
		- Convenient and readable syntax
		- Provides a more robust way to handle errors, such as handling missing keys or non-existent values
	+ Cons:
		- Requires an additional library (Lodash) to be included in the test environment
		- May introduce overhead due to the need for function calls and lookups
* **Native (Property dot notation)**:
	+ Pros:
		- No additional libraries are required, making it a more lightweight option
		- Can provide better performance in some cases, as it avoids the overhead of function calls and lookups
	+ Cons:
		- Requires manual error handling to avoid null pointer exceptions or other errors

**Library: Lodash**

Lodash is a popular JavaScript library that provides a set of functional programming helpers. The `_.get()` method is one of its many utility functions, designed to simplify the process of accessing nested objects.

The `_.get()` method takes an object and one or more keys as arguments and returns the value associated with those keys. If any of the keys are missing or non-existent, it will return undefined or null instead of throwing an error.

In the context of this benchmark, Lodash is used to provide a convenient and robust way to access nested objects without requiring manual error handling.

**Special JS feature: ES6 Optional Chaining**

The `_.get()` method uses ES6 optional chaining (`?.`) which allows you to safely navigate through nested object properties. The syntax `myObj.cars?.car1` returns undefined if `cars` or `car1` is null or undefined, instead of throwing a null pointer exception.

This feature provides an additional layer of safety and robustness when working with nested objects in JavaScript.

**Other alternatives**

If you don't want to use Lodash, you can also consider other libraries like Moment.js for date manipulation or React's `useMemo` hook for memoization. Alternatively, you can implement your own utility functions for accessing nested objects using native JavaScript syntax.
